China is quietly pushing ahead with massive 50,000Mbps broadband rollout to leapfrog rest of the world on internet speeds

China will be lucky if they still exist as a single unified nation. Demographics, employment, debt, over built property market, over dependence on manufacturing exports, energy import dependence, food import dependence.
They have a number of very strong headwinds that could very well cause the failure and break up of the CCP in the next twenty years.
Have you ever stepped food into China? I have. And I can tell you from personal experience they're living in the future.
They have their own fair share of problems. But the investments they're making into infrastructure are very easily going to catapult them to the head of the class here very shortly...
I'm really tired of being told how distopian China is from people who've never even been there.

So I'm just going to be a completely different person once I have access to these speeds or you are suggesting new tech that will be made available to consumers?
The second one.
Think back to when you were on dial-up. The concept of a streaming movie service would have been a fantasyland. No one was creating one. The infrastructure wasn't there. It was impossible.
As soon as people started getting broadband, and enough people got it, streaming services could exist.
Are you different? No, you just want to watch a movie. But now you don't have to go to Blockbuster.

That's entirely speculative. There are diminishing returns. Unless you're going to host your own YouTube, the use case for 50Gbps connections to the home is quite small. 4K video streaming at Ultra HD Blu-ray bitrates doesn't even come close to saturating 1Gbps, and all streaming services compress 4K video significantly more than what Ultra HD Blu-ray offers. The server side is the limit, not home connections.
Now, if you want to talk about self-hosting stuff and returning the Internet to a more peer-to-peer architecture, then you need IPv6. Having any kind of NAT in the way is not going to work. Connection speed still isn't that important.#
Unless you're going to host your own YouTube....
This is exactly what peer tube is struggling with. This bandwidth would solve the video federation problem.
See, you get it!

Except we need IPv6 before that's at all viable.
We are not even filling out the bandwidth of pipes we have to the home right now. "If you build it, they will come" does not apply when there's already something there that isn't being fully utilized.

Notice how many extra hoops you jumped through to get here
To arrive at "China Good," yes you do need to jump through many hoops. Glad we're on the same page, even if you started out strangely.

640kb should be enough for anybody.
640kb? Luxury.

I wonder if they use semiconductor optical amplifiers in the receivers, or if they can make do with avalanche photodiodes.
The 100G stuff I'm looking at has 18.5 dB budget with APDs, that seems rough considering you want a few kilometers of fiber, a few splices and a few connectors (probably LC/APC) as well.
I work on PON and XGPON. Officially we work on a -25dB maximum, but I've seen circuits stable at around 30dB.
It's surprising how many bad splices you can ignore before it gets problematic.
-18.5dB is going to limit you to either a really good fibre path, or a really short one. Unless you have options with long-range SFPs? The constant progress keeps my job interesting at least.

And then he blocked me XD
All these egotistical children with nothing to be proud of

Lmao the irony
You have serious ego issues that you will need self reflection to fix.

I'm working on long range stuff so I'm not so familiar with PON specifically. Maybe I made some bad assumptions. Stable at -30 dBm receive sounds really impressive.
The one I was talking about is this, with 18.5 dB total budget, that is, min +4.5 dBm transmit, and min -14 dBm receive. This one is built with an APD.
In my kind of application, without splitter, this will get you about 30-40 km. We've got one of a slightly older type with 18 dB budget running between Fribourg and Bern for example.
I realize that PON stuff is quite different with the time slitting and I think wavelenght splitting too, at least in XGS-PON, but I was thinking the pure laser and diode physics would need to be the same.
For -25 dBm minimum the most similar of the ones we currently have would be this one which manages -26.9 dBm and is one of the ones with a SOA built in, or for the 10G stuff this one, which manages min -23 dBm but with only an APD and no SOA.
I'm thinking their 50G stuff must be closer to 100G than 10G transceiver design. So I wonder if they manage to make it without SOA.

Man, real countries are doing this shit while the US is doing an illegal war on the thought crime of being"woke".
China has this covered hands down. If you say Winnie, two mean looking Chinese men appear behind you.

Oh, maybe. I'm not familiar with bandwidth utilization in China.

Very cool and they should keep doing this, but no one’s CPE is going to be able to do anywhere near this speed unless they plan on giving everyone large enterprises routers for home use.

Who blocked you?

Feel free to elaborate. I have no idea what you're talking about other than it seems like tankie screeching to me.

the us will be lucky if it exists at all in the future

Yeah, one thing at a time

We’ll be around. We may not be a democracy but we’ll be around.
China though, it’s cooked .

there could be some new thing that no one has not even bothered to think about because of the limitations. Imagine streaming back when downloading few kilobytes for an hours was considered reasonable, people would have laughed at the very thought of it.

360 VR experience with 16K resolution, highly textured touchable surfaces, and smell-o-vision. Only a $40 Meta subscription with ads.
. Only a $40 Meta subscriptio
I tried to upload some 8k 360 footage to FB before I left it
"We're sorry, but an error has occurred"Tried over several days, no good. tried again a month later, still no good.
Camera is more or less useless if you can't host the footage anyway
